Note! When using the RWF50… as a modulating controller only, or as a modulating controller without the burner
release function (1P, 1N), parameter HYS1 must be set to 0 and parameters HYS2 and HYS3 must be set to their maximum values.
Otherwise, for example, when using default parameter HYS1 (factory setting -5), the 3- position controller is only released
when the control deviation reaches -5 K.
